Product Description:

The DDC01.1-K150A-DS50-00-FW is a servo drive from Bosch Rexroth Indramat in the DDC Digital Intelligent Servo Drives series. It delivers regulated three-phase power to an AC servo motor in industrial automation cells. By converting rectified input power into controlled pulses, the drive enables coordinated speed and torque so that motion axes follow programmed profiles with consistent accuracy. Its control behavior suits multi-axis equipment where the drive must respond quickly to changing load conditions during indexing, positioning, or synchronized motion.

At the power stage, the inverter supplies a rated current of 150 A, while its continuous current remains at 90 A to keep the thermal load within limits. The unit can sustain a continuous mechanical output of 15 kW and absorb transient demands up to 25 kW, which suits rapid acceleration cycles and short overload periods. A continuous bleeder of 1.0 kW and a peak bleeder of 40 kW dissipate excess DC-bus energy, and a maximum regenerative absorption of 10 kWs helps protect the link capacitors during braking. This operating range helps the drive handle repeated starts, stops, and deceleration events in cyclic production duty. The supply section accepts a maximum connected load of 22.5 kVA, and the IGBTs switch at a pulse-width-modulation frequency of 4 kHz to balance current ripple with heat generation. Standard noise emission is specified for the 100 A to 200 A class, and internal power loss is 540 W that must be removed by the selected cooling method.

The housing uses natural convection air cooling, so installation must allow free airflow over the fins. With a protection category of IP65, the electronics remain sealed against dust and water jets when the drive is mounted outside a cabinet. Command signals arrive through a SERCOS interface module, and motor position is returned through digital servo feedback to close the velocity loop. This feedback arrangement allows the controller to maintain stable response during speed changes and commanded corrections. The product is series 1 and version 1. Its overall mass is 22 kg, which should be considered when fastening the unit to the machine framework.
